SPECIFICATION formingpart of Letters Patent No. 673,146, dated April 30, 1901.

Application filed December 12, 1898. Serial No. 698,998. (No model.)

To a, whmn it may concern.-

Be it known that 1, CHARLES E. VAN HORN, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Carbonators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to certain new and useful improvements in apparatus for carbonating liquids.

The primary object of the invention is to regulate the supply of liquid to the apparatus by the amount drawn OF.

A further object of myinvention is to carbonate liquids under a constant gas-pressure, with the inlet and outlet controlled by the liquid in the apparatus, the liquid being forced into the apparatus either by pump or air pressure and forced therefrom by the constant gas-pressure in the apparatus, which serves both to thoroughly impregnate the liquid with gas and to force the liquid from the apparatus into any suitable receptacle under any desired counter-pressure.

A still further object of my invention is to construct an apparatus for carbonating liquids of all kinds that will be purely automatic in every particular.

In describing the invention in detail reference is had to the accompanying drawings, forming a part of this specification, wherein like figures of reference indicate similar parts throughout the several views.

In the drawings, Figure 1 is a side elevation of my improved carbonator. Fig. 2 is an end elevation of the same. Fig. 3 is a vertical sectional view on the line X X of Fig. 1. Fig. 4 is a top plan view. Fig. 5 is a sectional view of an air-operated valve located in the inlet-pipe. Fig. 6 is a sectional view of the valve controlling the admission of the air to the air-operated valve.

Referring to the drawings by referencenumerals, 1 designates a horizontal cylinder forming an infusion-chamber, and 2 a vertical cylinder forming a carbonated-liquid re-/ ceptacle. The infusion-chamber 1 is mounted upon a suitable support 3, near one end on the underneath side thereof is a hollow casting 4, which is mounted on a suitable support 5, said hollow casting communicating with the infusion-chamber 1.

Secured to the hollow casting 4 and communicating therewith is a liquid-inlet pipe 6, in which is arranged an air-operated valve 7. Secured to the top of the infusion-chamber and communicating therewith is a hollow casting 8, which receives the gas from a supply-pipe 9. Arranged'in the top of the casting 8 is a relief-valve 10 of any suitable construction. Secured to the casting 8, on the opposite side thereof from the gas supply pipe 9, is a pipe 11, which leads to the top of a sight-glass 12. A pipe connects the lower endof the sight-glass 12 with the hollow casting 4. Secured to the pipe 11 is a pressuregage 14 of any suitable construction.

Journaled in the ends of the infusion-chamber 1 is a shaft 16, having connected to one end thereof a driving-wheel 17. Mounted on this shaft within the infusion-chamber l are paddles or blades 18, which are adapted to agitate the liquid, so that the same will become thoroughly impregnated with gas. The infusion-chamber is provided with a handhole 19.

Mounted on a support is the carbonatedliquid receptacle 2, between which and the support 20 is a hollow casting 21, communicating with said receptacle. From this casting 21 leads a liquid-discharge pipe 22, in which is arranged a sight-glass 23. Connecting the liquid-discharge pipe 22 and the pipe 15 is a pipe 24., which is adapted to drain the liquid from the infusion chamber 1'. Arranged on one side of the carbonated-liquid receptacle 2 and connected therewith is a sight-glass 25.

25 denotes a short shaft journaled in the receptacle 2. Fixed to this shaft within the receptacle is a lever 26, on which is a float 27. Secured to this lever 26 is a connecting-rod 28, the lower end of which is pivotally attached to a rock-lever 29, and pivot-ally secured to the lever 29, about midway of its ends, is a valve-stem 30, on the lower end of which is attached a balanced valve 31, movable to and from a valve-seat 32, the valve thereof, and secured to the opposite end and l and valve-seatheing located withinthehollow casting21.

One end of the shaft projects through and beyond one of the heads of the receptacle 2, and on said projecting end is fixed an arm33,-the object of which will be herei-nt after more fully described.

34 denotes a pipe bywhich air underco'm the pipe 34 is a valve-stem 38,-on theupperq end of which is secured a valve 39, adapted to engage the valve-seat. 36. The valve is" held normally against its seat by the air-pres sure and also bya spring "38. 'Secnred'to the valve-chamber is a pipe 34:, leading to the air-supply. (Not-shown.)

'Secured to thepipe '34 is a vertical pipe 4E0,

in the upper end of which is anescape valve 41. The function of this valve 41 is to relie've thepressure behind'the valve '7. The lowerend of said pipe is connectedtothe upper end'of a cylinder 42, which is-an 6X- tension of the casing of the valve7. lnthe cylinder42 a piston=head 43-operates. Se-

Theyobject in locating the passage as shown is to retain the liquid in=the infusion-chamberasufiicientlength of time to become thoroughlyimpregnated with gas before'it passes into the carbonated-liquid receptacle. The

carbonated-liquid receptacle is arranged be. low .the level of the infusionchamher, whereby sulficient space is given forfreeoper-ati'on of the float and also to establish a level of the liquid in the receptacle below that'established in the infusion-chamber.

Fllhe operation 'is as follows: Thesupply-= pipe 22 is connected to a storage-tank conta'iningsthe desired counter-pressure. Gas is chamber 1 until it'reaches the point of over- Arranged in theipipe 34;

.lowing the carbonated liquid to discharge through thepipe asffast asit enters the infus ion chaniber. Should the influx of liquid be greater than the quantity drawn off, the surplusaccumulates in the receptacle, raising the float 27 until the arm 33, which moves with the float, comes in contact with the valve- '.stem :38, whenthe valve 39islrai-sed from its seat 36, thereby allowing the air to pass through ton-head 43, forcing the piston rod -15 and balanced valve '46downward and'antoinati'ca'lly -shutting off the flow of liqu'idto the'infusion-chamber 1. When the accumulated liquid in the carbonated-1iquidre'ceptacle has heen red need, the float "27* descends; carrying the arm 33 out of 'engagement with *the rod 38=of the'valve 39. The-pressureo'f the air against the top of the valve, 5 together Wi t'h the spring 38*, closes the valve 39, thereby cutting offthe supply otau to the air=operated valve Maud allowing the tension of t'lresp'ri n g 50=to open said valve when thel-atterhas been relievedof the pressure behind it by opening the valve 41.

The supply of liquid to theginfus'ion-chamher is automatically regulated by the-diseharge'o'f the liquidfr'om the carhonatedliquidreceptacle. When the liquid isad-mitted to the apparatus, no further attention is required.

It-will be noted that anyliqu-idmayhe 'c'arbon'ated in the apparatus above described, the only change required being the negulating of the gas-pressurein the-infusiomch amher in inverse pro'portionto the specific gravity of the-liquid to'be carbonated.
